Keyboard Instrument Front Screw Mounting Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic keyboard instruments require users to crawl under the instrument to fix the stand, which complicates the assembly process and degrades workability.
Innovation Solution
A keyboard instrument design featuring a stand with guide rails and fixing members that allow for easy assembly by positioning the instrument main body without the need to crawl underneath, using a combination of guide rails, fixing sections, and screw members that securely attach the instrument to the stand from a more accessible angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the instrument main body is fixed to the stand by inserting screws from underneath through L-shaped fixing brackets, then the instrument main body can be securely mounted on the stand, but the assembling person needs to crawl under the instrument main body which degrades assembling workability
Solution Approach 1:
The patent inverts the traditional screw insertion direction by providing screw insertion holes in the front and rear surfaces of the fixing sections instead of from underneath. This allows screws to be inserted from the front or rear of the instrument main body, eliminating the need to crawl underneath while maintaining secure mounting through the same fixing brackets and guide concave sections
2Reliability
If the instrument main body is fixed by crawling underneath to access the bottom surface, then secure mounting is achieved, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The patent changes the screw insertion direction from underneath to front/rear surfaces, allowing assemblers to work from accessible positions. This inversion eliminates the need to crawl underneath the instrument main body, significantly reducing assembly time while maintaining the same fixing reliability through the established bracket and guide concave section structure
3Reliability
If L-shaped fixing brackets are used on the side plates, then the instrument main body can be fixed to the stand, but the assembler must position themselves in an awkward position to perform the fixing
Solution Approach 1:
The patent inverts the screw insertion approach by providing holes in the front and rear surfaces of the fixing sections rather than requiring access from underneath. This allows assemblers to insert screws from comfortable positions at the front or rear of the instrument, eliminating awkward positioning while maintaining secure fixing through the same L-shaped brackets and guide concave sections

AI summary
A keyboard instrument includes an instrument main body having a keyboard unit, a stand which supports the instrument main body, main body fixing sections which are first fixing members for fixing the instrument main body to the stand, side plate fixing sections which are second fixing members for fixing the stand to the instrument main body, and front side screw members each of which is a third fixing member for fixing one of the main body fixing sections to one of the side plate fixing sections with them corresponding to each other in the front-rear direction of the instrument main body. Accordingly, in a state where the stand is supporting the instrument main body, each main body fixing section and each side plate fixing section can be fixed to each other by one of the front side screw members being screwed thereinto from in front of the instrument main body.
